產品描述：

小鼠蛋白質二硫鍵異構酶(P4HB)酶聯免疫試劑盒（CSB-EL017342MO）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的P4HB含量。P4HB 即脯氨酰 4-羥化酶β亞基，是內質網內的多功能蛋白。其參與膠原蛋白合成，對維持細胞外基質穩定至關重要。在研究機制上，它作為伴侶蛋白促進蛋白質折疊，還參與氧化還原反應。P4HB 與多種疾病相關，是潛在的治療靶點。試劑盒檢測范圍為0.312 ng/mL-20 ng/mL，為研究蛋白質折疊調控機制、氧化應激相關疾病模型（如肝臟疾病或代謝異常）以及內質網功能相關分子通路提供可靠工具；適用于體外實驗中探索P4HB在細胞生理病理過程中的表達變化及其分子互作研究，滿足基礎科研中對目標蛋白定量分析的需求。本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

精密度：

Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.

線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of mouse P4HB in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:1	Average %	94
	Range %	87-98
1:2	Average %	103
	Range %	96-108

靶點詳情

功能：

This multifunctional protein catalyzes the formation, breakage and rearrangement of disulfide bonds. At the cell surface, seems to act as a reductase that cleaves disulfide bonds of proteins attached to the cell. May therefore cause structural modifications of exofacial proteins. Inside the cell, seems to form/rearrange disulfide bonds of nascent proteins. At high concentrations, functions as a chaperone that inhibits aggregation of misfolded proteins. At low concentrations, facilitates aggregation (anti-chaperone activity). May be involved with other chaperones in the structural modification of the TG precursor in hormone biogenesis. Also acts a structural subunit of various enzymes such as prolyl 4-hydroxylase and microsomal triacylglycerol transfer protein MTTP. Receptor for LGALS9; the interaction retains P4HB at the cell surface of Th2 T helper cells, increasing disulfide reductase activity at the plasma membrane, altering the plasma membrane redox state and enhancing cell migration.
